Introduction to ZhenAn's Silicon Metal
With over 98.5% Si content and controlled impurity levels below 0.5%, ZhenAn International's metallurgical-grade silicon metal (Si ≥98%) serves as the essential raw material for aluminum alloy enhancement. Our material demonstrates exceptional fluidity during smelting processes, increasing alloy strength by 15-20% while maintaining ductility. The uniform particle size distribution (10-100mm standard, customizable) ensures precise dosing in foundry operations.
The 553# and 441# grades remain our bestsellers, with 553# containing max 0.5% Fe, 0.5% Al, 0.3% Ca, and 441# maintaining tighter tolerances at 0.4% Fe, 0.4% Al, 0.1% Ca. Both grades comply with GB/T 2881-2014 and ASTM C989 standards, making them compatible with global smelting protocols.
